get_auc: Determine Area Under the Curve

In dami82/CellSignalingTools: Analysis of Images for Molecular Biology Applications

Description

Determine the area under the curve given a numeric matrix containing position values (x-axis) and signal intensities (y-axis).

Usage

get_auc(signal_matrix)

Arguments

signal_matrix

is a numeric matrix containing two columns.

Details

The numeric matrix passed as argument must contain only two columns. The first column defines the position on the x-axis. The second column provides the signal intensity values (y-axis). The base is set at 0.

Value

Returns a numeric value corresponding to the area under the curve
